DISK PLOW.

Specification of Letters Patent.

Application led August 15, 1916. Serial No. 115,013.

To all whom t may concern:

Be it known that I, CHARLES T. RAY, a

`citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented new and useful improvements in Disk Plows, of which the following` is a specification.

This invention has particular reference to improvements in mountings for the rotatable ground treating disks of tillage implements, especially of those implements 'whose disks are arranged to turn the soil,-

plows, for examplef-and embodies novel features of construction and combinations of parts substantially as hereinafter described and particularly set forth in the appended claims.

One of the most important objects of the invention is to provide a mounting which will enable the angle of inclination of the disk with respect to a plane erpendicular to the surface of the grounc to be quickly changed and cause the disk to be held securely in its new position.

Another of the more important objects of the invention is to provide a disk bearing of simple and practicable construction which maybe easily and readily put together and taken apart and in which the disk journal will rotate with a minimum of friction.

These objects, and others, are secured in the construction illustrated in the accompartying` drawings, wherein:

Figure 1 is a perspective view of a preferred embodiment of the invention, viewed from the rear.

Fig. 2 is a detail sectional view on a line vertically through the axis of the ldisk andy disk carrier.

Similar characters of reference denote corresponding parts in both figures.

A disk plow hasbeen selected to exemplify the invention, this being the preferred application thereof: A designates a part of the frame, which may 4be of any suitable construction, B the concave-convex furrow turning disk such as is usually employed in plows of this type and C the scraper commonly used with such disks. These disks, particularly when employed in soil-turning implements,-as plows, for example,-are commonly set at an angle to the line of draft and it has 'been proposed to provide for their adless land. The present invention iis not essentially concerned with any adjustment of the disk upon a vertical axis, 'but is essentially concerned with an adjustment of the disk upon an approximately horizontal axis to vary its pitch. In a soil-turning' implement, as a plow, for example, the disk is so disposed that its outer peripheral edge is in a plane diagonal to the line of draft, as indicated by the drawing.

In this particular exemplification of the invention the frame is provided with a member 10, suitably arranged to carry a support or standard 11, which depends therefrom at an apropriate angle. The support or standard 11 has a channeled Aportion 12 which receives theframe-member 10, the upper and lower lips 12a at opposite sides of the channel in said portion 12 engaging the upper and lower surfaces of the frame member 10. It is also preferably formed with a ylongitudinal lin 13 and, as shown, is preferably secured to the frame-member 10 by throughlfiiolts 14, 14 disposed on opposite side of the The disk B is secured to a backing- 15 arranged at the axis thereof and this backing is provided with a rearwardly extending spindle 16, which forms the journal for the disk. This journal extends into a socket 17a formed longitudinally in a disk carrier 17. The carrier is also, preferably, formed to receive antifriction rollers 18, as hereinafter more particularly set forth.

The disk-carrier 17 is pivoted so that it may be moved upon an axis intermediate its ends, the said axis being` approximately horizontal and preferably substantially at right angles to the axis of rotation of the disk and preferably at an angle to the line of draft, tothereby change the position of the disk with reference to a plane perpendicular tov the surface of the ground without altering its angular relation to the line of draft, and is provided with means whereby this change in the position of the disk may be readily accomplished and the disk fixedly secured in the new position, said means being' preferably of such 'nature that the disk may be quickly moved to and effectively held -in any one of a series of selected positions lof adjustmontaround said axis. j

In thisexemplification of the invention the disk carrier is mounted upon an approximately horizontal` pivot bolt 19, which-is oblique with relationy to the line of draft `of Patented July 29, 1919.

the implement and extends through an opening v17b in the carrier and through correspondingopenings in the lower end of the support 11, the support being preferably bifurcated at 11c and the carrier preferably having a lug 17C to enter the bifurcated poras shown.

The adjusting and 4securing means prefer"n ably employed'consists of as member-as the threaded rod 20, for example-whose lower end ispivoteds-as-by the pivot 20L-to the rear endwof the diskecarrier- 17 and whose upper* end -is provided'V with means-as the nuts 21, 215,forgexainple-s-bywhich it .may be-securedrin: different positions Vwith relaL tion toy appropriate fixed part ofthe structures-thefbracket 22- for example-.- In this exennplicationk of the invention, the bracket 22 is mountedlon thefsi-de vof the franie` inem-ber" 10 opposite the channeled portion 12; ofthe support 11=and has anupper lipf22f"L toengage theuppersurface of said frameinenrber, and isfsecured byi the same boltsflrwhich: secu-re the support 11.y The bracketihiasa niemberl22? through which the rodv 20 e-xtends. Owingto the'pieculiarann gular disposition of! the parts, this member 22.b is preferably arranged at an angle to the horizontal flange 22c of' the. bracket.
